'Dancing With the Stars': Fantastic hunk William Levy scores

"Dancing With the Stars"on Monday served up some of its best dancing ever. The spirits were high, and so were judges' scores. One misstep could have been costly.

William Levy and Cheryl Burke delivered a tango filled with flashy footwork and fierce attitudes. "Occasionally a little bit flat-footed, but great job," Len Goodman said. "You were like the dictator of the tango," Bruno Tonioli told Levy. Carrie Ann Inaba liked what she saw but pointed out flaws, drawing the audience’s boos. Points: 28, with 10 from Tonioli.

On a snappy quickstep, Katherine Jenkins played a moll freed by gangster Mark Ballas and made like an exuberant flapper. Tonioli saw "amazing technique." Goodman spotted a foot fault but called the dance "fabulous." Inaba confused the studio audience, sounding critical before ruling it might have been the best dance she'd ever seen on the show. Really. Points: 29, with 9 from Goodman.

Donald Driver showed graceful and tender sides on a pretty waltz, although smoke on the floor was distracting. The judges were mostly complimentary, although Inaba cited flawed footwork. "You’re like a big, rough, tough cream puff," Goodman said. Points: 28, with 10 from Tonioli.

Maria Menounos and Derek Hough pulled off an Argentine tango that was the showiest and most exciting dance of the first round. "Utterly fabulous," Tonioli said. Points: 30, perfect marks.

In round two, Levy had no trouble shaking his body or turning on the suave charm on a crowd-pleasing samba. "Talk about the hunk with the junk in his trunk," Goodman said, praising the "fantastic" rhythm. Points: 30, perfect marks.

Jenkins shook her body seductively on a salsa with an Arabian nights theme, but she had a problem at the end. It wasn't clear what happened, although Ballas might have kicked his partner. The judges praised most of the dance, then turned comforting about the mistake. "Katherine the great," Goodman said. Points: 27.

Driver and Peta Murgatroyd strutted through a cheerful, sexy samba, but the dance wasn't as smooth as Levy's version. Even so, Inaba said it was "A plus game." Points: 29, with 9 from Goodman.

Menounos kept up with Hough on an exuberant jive that was a showcase for his dance brilliance. The judges were wowed, although Goodman spotted a mistake. Points: 29, with 9 from Goodman.

As the show ended, host Tom Bergeron revealed that Jenkins would have her lower back checked.

The results will be revealed in a telecast that starts at 9 p.m. Tuesday on WFTV-Channel 9. Carrie Underwood and Alanis Morisette will sing. Who goes? Jenkins, so often the leader this season, seems most vulnerable.
